Trying to make better use of books I already have, I am tickled when I look up an ebook that sounds interesting and get a banner across the page that says I bought the book in question 6 years ago. That means I already have it and Amazon won't sell me another ecopy. I can send one to a friend but the copy I have is the only Kindle copy I will get. The book, "Positive Psychology" by Ronald Siegel and others is published by Harvard University and summarizes ideas and research about what lifestyles and habits promote happiness and I was informed I had bought the book years ago. And never downloaded it or read any of it.
Reading it, I found the question "Remember how happy you were when you got a raise?" It went on to state that probably I wasn't as happy now over that raise as I was when I first found out about it. So, happiness (and delight and excitement levels) deteriorate over time. I told my friend about reading that and he said he loves to relive the past and that he achieves the same happiness when he recalls a past happy as he had when he first felt it. I take this to be a warning and a challenge! Do you think I am going to just accept inferior subsequent happiness levels? No way!
I am going to study me and my memory and my past happiness peaks and look into doing better at duplicating them later in time. I'll let you know how I do.
